BUSH FOR VERTICAL SHAFTS.

SPECIFICATION forming part of Letters Patent No. 275,867, dated April17, 1883.

Application filed May 15,1882.

To all whom tt may concern:

Be it known that we, PHILIPP S'rEINMETz and JOHN GEISINGER, citizens ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Bushes for Vertical Shafts, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, wherein- Figure 1 is a vertical transversesection of our improved bush. Fig. 2 is an elevation of same. Fig. 3 isa plan, partly sectional, with top plate removed; and Fig. 4 is a planof the frame or box of the bush.

Our invention has relation to bushes for vertical shafts, and isespecially adapted for mill-spindles.

It has for its object to provide a bush wherein the followers are soarranged within the bush that they are free to move laterally oradjustthemselves to the shaft or spindle, and thereby form aself-adjusting bush.

Our invention has for its further object to provide a self-oiling bush.

Our invention accordingly consists of the novel combination,construction, and arrangement of parts, as hereinafter more specificallydescribed and claimed.

Referring to the accompanying drawings, A represents the bush box orcase, which may be circular in outline or ofany other suitable shape, I

having a central aperture, a, for the shaft or spindle B.

O 0 represent two sets of chambers formed in said bush, surrounding theopening a. The chambers O O O are oblong in outline, as shown, and haverear inclined sides, 0. In said chambers are placed the loose followersD D D, the rear sidesof which are inclined,as shown at 6?, Fig.1.

E E E represent bearings for said followers, and are formed with curvedor convexed sides 6 e which respectively rest or bear against theinclined sides 0 d of the bush and followers. Said bearings are held inposition and vertically adjusted to take up the wear of the followers bymeans of the screws F F, which pass (No model.)

through the bottom a of bush A, and enter openings or recesses e in saidbearings. By turning the screws F F the bearings E E are raised in thechambers O G, whereupon, ow-

ing to the inclination of the sides 0 d, the followers D D are caused tohug the spindle B and form a bearing therefor, while the rounded orcurved sides e of bearings E form pivotal points for the followers D Dto rock upon, in order that they may automatically adjust themselves toany lateral movement of the spindle B. The chambers G G O are segmentalin outline, and have vertical central openings or lines of perforations,0 through which oil or other lubricant contained in said chambers findsits way to shaft B.

Gris a stuffing-box upon the bottom a of the bush, as shown in Figs. 1and 2, for preventing leakage of oil from chambers O; and A is a cap orcover for the bush, screwed or otherwise suitably fastened thereto.

If the bush is designed to be applied to mill spindles, it may be formedwith lugs A A for securing it to the millstone; or the bush may bewedged to the stone in the usual manner.

If desired, the chambers O 0' may be filled with waste and oil, tallow,lard, or other lu-- other being adapted and designed to hold alubricant, said bush having a stuffing-box applied thereto,substantially as shown and de scribed. I

2. A bush or bearing, A, having inclined side 0, the followers D D,interposed bearings E E, having curved or rounded sides 6 e, recess 0and the adjusting-screws F, substantially as shown and described.

In testimony whereof we affix our signatures in presence of twowitnesses.
